In a host of industries—from automotive assembly to food processing to oil refining—industrial process control applications require solutions to the growing demand for feature-rich, high performance, highly reliable semiconductor components. The increase in sensor and actuator usage has resulted in tighter control of open- and closed-loop processes, leading to improved systems for asset management, building control, measurement, and programmable automa-tion. This brochure features recently announced signal path ICs that are ideally suited for demanding indus-trial environments within current and future industrial control systems.

Measurement and control implementations exist in several industrial applications, including programmable logic controllers (PLC), distributed control systems (DCS), smart transmitters, and general-purpose data acquisition. Their purpose is to leverage various types of sensors and feedback mechanisms to monitor and control machine or system interactions by collecting, storing, and analyzing data. Acquiring data from sensors involves precision measurement and processing of analog variables, such as voltages and currents, where there is a need to often sense very small changes. Typical devices used in the input signal chain are amplifiers, multiplexers, isolators, and ADCs. Accuracy, drift, noise rejection, and processing speed are all very important characteristics in these systems. System requirements for accuracy, bandwidth, and input range dictate the selection of not only the choice

of signal chain components but also power supply components.

A DSP or microcontroller is commonly used to process the digital signals for display or analysis. Once process data has been appropriately conditioned and digitized, an appropriate action normally takes place. This action occurs in the output signal chain. A response is fed into a DAC, which can control or manipulate the appropriate actuator, pump, or valve, or simply transmit data over the 4 mA to 20 mA control loop, depending on the desired result.

If the system resides in a harsh industrial environment, safety measures require not only an isolation barrier that prevents ground loops but operation that is intrinsically safe as well. Isolation devices are used to protect against high voltages or currents caused by line surges, which can introduce noise, degrade measurements, and even destroy system components.

Analog Devices—with a broad selection of analog, power, and interface ICs—is positioned to deliver world-class processing solutions to our customers and continues to invest heavily in the industrial market with innovative new product families. With our new data converters, operational amplifiers, isolators, interface ICs, and power products, you’ll find solutions inside that will achieve the performance requirements of your current and future industrial control systems.

ADA4091-2: 36 V Micropower R-R I/O Op Amp with Overvoltage Protection (OVP)Sensor input amplifiers in systems such as PLCs are often subjected to transient or fault voltages that may exceed the supply voltage of the amplifier and can damage the amplifier and/or other circuitry or may cause spurious output conditions that could cause system lockup or damage. The ADA4091-2 integrates circuitry that protects the amplifier from damage and prevents phase inversion errors. Amplifier performance is fully specified, including the protection circuits, eliminating the need to account for the effect of errors from external components on system performance.

External protection devices are reduced, saving system cost and reducing PCB space requirements. The low power and small form factor make the ADA4091-2 ideal for both multichannel systems and space-constrained applications. Low offset, low offset drift, and wide GBW allow accurate signal conditioning of a wide variety of sensor inputs. It is avail-able in 8-lead LFCSP and 8-lead SOIC.

ADP1621: Solving Power Distribution Problems in Industrial Equipment with ADI Power RegulatorsTypical industrial control systems include a set of analog input/output modules that operate from ±15 V supplies and interface with industry- standard 4 mA to 20 mA control loops. Such power supplies are easily generated from the versatile synchronizable ADP1621 switching controller enabling ADC clock aperture synchronization to the quiet period of the switching frequency.

The control of the system is normally made up of a set of processors, memory, and FPGAs often powered from 3 V supplies with additional lower voltage inputs for core processor power. Generation of the 3.3 V rail is accomplished very efficiently with a switching regulator such as the ADP3050—minimizing external parts count. The local core voltage is easily generated from the low dropout ADP1706 linear regulator that provides stable operation with compact multilayer ceramic capacitors.

Analog Devices now makes it easier then ever to support system level design with magnetic components using ADIsimPower™ design tools that produce ready-to-go designs for linear regulators, switching controllers, and regulators. For more information, visit www.analog.com/ADIsimPower.
